Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers excellent anti-aging benefits for your dry skin, as Sh-Oligopeptide-1 and Adenosine work to minimize fine lines and wrinkles, while Glycerin and Blueberry Fruit Extract provide essential hydration and antioxidant support.
- The formula is highly suitable for your dry and sensitive skin, with humectant and antioxidant properties that help hydrate and protect.
- The safety profile is excellent, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.
